Problems solved by technology

[0003] At present, gesture numbers are generally used to input numbers with different gestures. It first recognizes gesture images, and then interprets different gestures as different numbers. The main problems of this method are: (1) The recognition rate is affected by many factors. (such as distance, feature extraction, recognition operator, etc.), especially for gestures with similar shapes, it is difficult to distinguish them by ordinary methods; (2) when multiple people operate at the same time, they are easy to interfere with each other; (3) there is a "MidasTouch problem"

Embodiment Construction

[0044] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0045] (1) Virtual interface

[0046] By analyzing the operator's gesture operation behavior, the computer can form a gesture interaction sensing area in front of the operator, which may be two-dimensional (2D) or three-dimensional (3D), and it can follow the operator's body position or The change of posture changes step by step, as if there is an invisible operation screen near the operator's gesture that can change with the movement of the operator's body. The present invention refers to this operator's gesture operation area with specific structure and function as (Intangible) Virtual Interface (TI). Divide the virtual interface into several sub-blocks, combine multi-modal gestures (ie, 2D interface gestures / 3D interface gestures, communication gestures / operating gestures) to build basic interactive functions, and build the basic interactive functions between thes...

Abstract

The invention provides a digital input method based on gestures and belongs to the field of computers. According to the method, a virtual interface which is an operator gesture operation area is constructed and can change along with the body position or the posture of an operator; N digits are sequentially input through the virtual interface, or N virtual interfaces are generated, one digit is input into each virtual interface, and the N virtual interfaces form a virtual interface group; a display screen is defined as a physical interface, and the space between the operator and the physical interface is defined as a physical space; the physical space comprises the virtual interface and a non-virtual interface; the gestures of the operator are effective and perceptible within the virtual interface and ineffective within the non-virtual interface; the digits are input through the virtual interface group.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a gesture-based digital input method. Background technique [0002] Inputting numbers with gestures has always been one of the difficult and key issues in gesture interaction theory and application research, and it is also one of the pain points in industrial fields such as smart home appliances. [0003] At present, gesture numbers are generally used to input numbers with different gestures. It first recognizes gesture images, and then interprets different gestures as different numbers. The main problems of this method are: (1) The recognition rate is affected by many factors. (such as distance, feature extraction, recognition operator, etc.), especially for gestures with similar shapes, it is difficult to distinguish them by ordinary methods; (2) when multiple people operate at the same time, they are easy to interfere with each other; (3) there is a "MidasTouch problem" ....
